A trio of bank robbers led New Rochelle cops on a wild high-speed chase into the Bronx, where the stickup suspects crashed before being nabbed by cops, police said.

Two of them, dressed in black, stormed into Webster Bank at 2 River Street at 12:17 p.m., police said. The heavier of the two goons threatened customers and employees with a long-barrelled handgun while the thinner of the pair demanded money from a teller, who hit a panic button, cops said.

Witnesses said the robbers ran off with a bag full of cash and a dye pack, then jumped into a waiting blue SUV with Pennsylvania plates.

New Rochelle police chased the SUV southbound on I-95 to the Hutchinson River Parkway, where the trio ditched the gun, swiped an exit barrier and ricocheted off the road, where the SUV came to a stop and cops pounced.

Police said they recovered a bag of money and a mangled gun that was struck by several cars. No injuries were reported and the suspects weren’t immediately identified.
